High-resolution photoelektron momentum microscopy of organic charge-transfer salts at variable temperature (B08)

该项目的重点是通过应用一种称为飞行时间动量显微镜的角度分辨光电发射的新方法来确定有机电荷转移盐的电子结构。这提供了价带结构及其与温度的关系，同时在相关的能带和完整的布里渊区，具有最小的辐射损伤和高的空间分辨率。K-(BEDT-TTF)2X和TMTTF2X晶体的计算结果将与理论计算结果进行比较。基于同步加速器的NEXAFS和HAXPES提供了关于电荷转移过程细节的补充信息。

The project focuses on the determination of the electronic structure of organic charge-transfer salts by applying a novel approach of angle-resolved photoemission, called time-of-flight momentum microscopy. This gives access to the valence band structure and its temperature dependence, simultaneously in the relevant energy band and the full Brillouin zone with minimum radiation damage and high spatial resolution. Results for k-(BEDT-TTF)2X and TMTTF2X crystals will be compared with theoretical calculations. Synchrotron-based NEXAFS and HAXPES yield complementary information on details of the charge-transfer process.
